I don't think Amaterasu could burn the core before it sucked him in, if you mean repel it with Shinra Tensei then yes, but I don't think Itachi could use 3 Amaterasu's one after another could he? It does take a considerable amount of chakra...sigh. Obviously Itachi.
If Tendo forms Chibaku Tensei, Itachi ignites it and him with Amaterasu. If Tendo repells it with Chibaku Tensei, Itachi will immediately use it again, seal him with Totsuka no Tsurugi or kill him with Yasaka no Magatama. Genjutsu works as well, and summoned crows are a good way to distract Tendo and force him to use Shinra Tensei, too. Way too many opportunities for Itachi..![]()
I don't see Itachi rushing into Susano'o so I don't think he'd seal him straight away, I don't see Deva falling for Itachi's famously powerful gejutsu to easily, and he definitely wouldn't waste a Shinra tensei on crows.
I think it may come down to if Itachi cast's Susano'o first, or if Deva casts Chibaku first.
